The most recent findings on the use of alginate as a biopolymer in diverse biomedical applications and therapeutics are examined in this new volume. Tissue regeneration, drug encapsulation and delivery, nucleic acid materials, proteins and peptides, genes, herbal therapeutic agents, nutraceuticals, and more are among the applications of alginates and modified alginates covered in this book. The synthesis and characterization of numerous alginate and modified alginate systems, including scaffolds, hydrogels, gels, composites, nanoparticles, and others, are also covered in this book. utilized in therapeutics and biomedical applications. Alginate is a naturally occurring biopolymer that has a wide range of uses in materials science and pharmaceuticals, including as medical diagnostic tools. Being one of the most prevalent natural biopolymers, it is regarded as a superior excipient due to its stable, biodegradable, and non-toxic characteristics. Numerous advancements in alginate applications for biomedicine and drug delivery have been made in research. For alginates and their derivatives to be useful in the healthcare industry, a full grasp of their synthesis, purification, and characterization is required. This volume provides a wealth of information in that direction.
